But 18 and 19 year olds are not kids you idiot they are both legally considered an adult in most parts of the world

But you’re still ignoring the huge difference in power dynamic. Unless you want that, in which case I can’t see how you could call that moral.

Obviously I would never have sex with 16 and 17 year old woman because they both considered minors which makes it morally wrong for me to have sex with them because I’m an adult.

Since you still struggle with the morality of the sexual power dynamics of having sexual relationships with those too young to understand the concept, it’s clear that it’s not any sense of morality stopping you— it’s the legality.

I have no doubt you’d fuck kids if you didn’t fear the legal consequences.
